To all, whom it may concern:

Be it known that I, LEMUEL PATTERSON, a citizen of the United States, residing at Olean, in the county ofCattaraugus and State of New York, have invented new and useful Improvements in Wall-Plugs, of which the following is a specification. I

This invention relates to Wall-plugs; and the primary object of the same is to provide an inexpensive device of this class for use in brick, stone, or concrete-block buildings to serve as means for holding strips to receive lathing, or for other purposes, such as to secure and finish door and window casings, base-moldings, trimmings, &c.

The invention consists in the construction and arrangement of the several parts, which.

will be more fully hereinafter set forth.

' In the drawings, Figure 1 is a perspective view of a portion of a wall, showlng the improved plug disposed therein. Fig. 2 is a detail perspective view of the improved plug.

The plug 1 is formed with-a wedge-shaped body having the reduced end thereof longitudinally cut or kerfed, as at 2, to'receive' nails. The maximum thickness of theplug is approximately the same as the distance between courses of bricks,.blocks, or stones ordinarily occupied by mortar, cement, or

other analogous material, and in building a erf extremity also has a side exposure, as,

shown by Figul of the drawings.

It will be understood that the improved plug will be formed from wood or analogous material, into which nails can be driven, but it is preferred that some cheap material be used adapted for the purpose and the plugs manufactured in bulk andshipped in boxes or barrels or otherwise prepared and transmitted as may be desired. In all ap lications of the plug the-thickened extremity or the end having the maximum vertical extent will be disposed in the inner part of the wall and the reduced extremity projected outwardly or terminated flush with the wallface except when used at a corner of the wall,

and under the latter conditions, as heretofore specified, the one side edge of the plug will also be exposed.

It will be seen that strips of every description may be readily attached to the plug by driving nails therethrough, which are caused to enter the slot 2 and operate to expand the latter and tighten the wedge between the courses of bricks or blocks, and thus set up a material resistance to the loosening of the wedge, as will be readily appreciated. It will also be understood that the proportions and dimensions of the plug may be varied at will,

and in view of the simplicity of the construction of the same it can be manufactured at a small cost.

What I claim is' 1. As an improved article of manufacture, a wedge-shaped wall-plug having its reduced extremity longitudinally out to provide separating members, the said members being normally in contact with each other throughout the full length of the cut and of a yielding nature.

2. As an improved article of manufacture, a wedge-shaped wall-plug having its reduced extremity lon itudinally cut toproduce expansible mem ers, said members being normally in contact and expanded by the introduction therebetweenof a fasteningdevice.

3. The combination with a W8.ll,0f8. wedgeshaped plug inserted between the courses of the members of the wall with its largest extremity innermost, the said plug having its outer reduced extremity longitudinally cut to provide expansible' members, said members being normally in contact throughout the-length of the cut and separated by the introduction therebetween of a fastening dev1ce.

In testimony whereof I aflix my signature in presence of two'witnesses;

LEMUEL PATTERSON.
